(PLEASE HELP !!) 1. Diploid refers to

A. a cell that contains a single copy of homologous chromosomes as seen in
reproductive cells.

B. a cell that contains both sets of homologous chromosomes (the full number of
chromosomes) as seen in cells of the body.

C. a cell that contains half the set of homologous chromosomes (reduction of
chromosomes) as seen in cells of the body.

D. a cell that contains twice the number of nuclei.

Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
